I'm looking for video support on OMAP4 platforms. I've found the

issues with setting up the pipeline, etc.
Can this list help out?
I'm not sure exactly what kind of cameras you want to get working, but
if you are looking to get CSI2 cameras going through the ISS, Sergio
Aguirre has been working on support. He also works on the media-ctl
tool, which is used for configuring the media framework pipeline. The
latest versions that I am aware of are here:
git://gitorious.org/omap4-v4l2-camera/omap4-v4l2-camera.git
Yes, this is the tree I've been working with (pointed to by the page I mentioned).
My kernel can see the camera OV5650 and set up the pipeline. I am able to grab
the raw SGRBG10 data but I'd like to get the ISS to convert this to a more usable
UYVY format. Here's what I tried:
media-ctl -r
media-ctl -l '"OMAP4 ISS CSI2a":1 -> "OMAP4 ISS ISP IPIPEIF":0 [1]'
media-ctl -l '"OMAP4 ISS ISP IPIPEIF":1 -> "OMAP4 ISS ISP IPIPEIF output":0 [1]'
media-ctl -f '"ov5650 3-0036":0 [SGRBG10 2592x1944]'
media-ctl -f '"OMAP4 ISS CSI2a":0 [SGRBG10 2592x1944]'
media-ctl -f '"OMAP4 ISS ISP IPIPEIF":0 [SGRBG10 2592x1944]','"OMAP4 ISS ISP IPIPEIF":1 [UYVY 2592x1944]'
Sadly, I can't get the IPIPEIF element to take SGRGB10 in and put UYVY out (my reading
of the manual implies that this _should_ be possible). I always see this pipeline setup:
- entity 5: OMAP4 ISS ISP IPIPEIF (3 pads, 4 links)
type V4L2 subdev subtype Unknown
device node name /dev/v4l-subdev2
pad0: Input [SGRBG10 2592x1944]
<- 'OMAP4 ISS CSI2a':pad1 [ACTIVE]
<- 'OMAP4 ISS CSI2b':pad1 []
pad1: Output [SGRBG10 2592x1944]
-> 'OMAP4 ISS ISP IPIPEIF output':pad0 [ACTIVE]
pad2: Output [SGRBG10 2592x1944]
-> 'OMAP4 ISS ISP resizer':pad0 []
Am I missing something? How can I make this conversion in the ISS?
Note: if this is not the appropriate place to ask these questions, please
redirect me (hopefully to a useful list :-)
Thanks
